This is the most fun and natural integration of ecology, science, art, and history.  Based on the more than 2,000 year old Asian practice, you become part of the entire process of re-using old paper to make new.  
 
MAKING SHEETS OF PAPER:
Why it is INTENSIVE:
Preparation, set-up, and break down takes approximately 40 minutes.  One instructor helps two participants at a time pull sheets of paper from the tub while small groups rotate through a series of "jobs" relying on one or two adults for group management.  Time needed to rotate through the group will vary, and 1-3 adults helping with young folks is suggested.
 
Some preparation and basic materials are required.

2 to 2-1/2 hours depending on group size
Best for age 5 years to adult
 
MAKING SEED PAPER BALLS or SEED PATTIES:
Each person creates a ball or patty of wet paper pulp and seeds, pressing and squeezing water out, and maybe even swinging it around outside (it's physical).  See image #4. 
 
1 to 1 -1/2 hours depending on group size
Best for age 7 years to adult
